RE: Formalin substitutes.... (again!)

From:"Tom T. McNemar" <>

I was really hoping to go the other way around..... I would prefer to get
rid of formalin altogether but that is unlikely.  I would rather be able to
give the substitute out to the offices and other sites and keep the formalin
in the lab.  Formalin is such a hassle.  The offices and even some sites in
the hospital are just sure that formalin is an instant killer. Training in
formalin precautions is an ongoing process but it seems like I am
continually providing MSD sheets, explaining, etc.
